hey guys , my name is john. I was wondering if anyone has ever done the 4 hi headlight mod to an older chevy? i have a 1983 blazer and just installed the heavy duty harness from LMC , I have heard of people using a relay or a diode to accomplish this , but am unsure of how to wire it into the headlight system correctly! if anyone could explain how to do it or provide a wiring schematic to show me how i would appreciate it very much! thanks
